DESCRIPTION
The EV1527DR-02A evaluation board is
designed to drive a single Lumileds LED with
low, forward voltage for Camera Flash
applications. The board is set up to obtain
150mA torch current and 750mA flash current
with an input voltage range of 3.0V to 4.2V. The
torch and flash currents can be adjusted by
resistors R2 and R3 on the Evaluation Board.
The MP1527 switches at 1.3MHz and allows
the use of tiny, low cost capacitors and small
inductors. External compensation and soft-start
result in small inrush current and extend the
battery life. The MP1527 operates from an input
voltage as low as 2.6V.

EV1527DR-02A - 1.3MHZ LOW POWER LED TORCH/FLASH DRIVER
EVALUATION BOARD
QUICK START GUIDE
1. Connect a Lumileds DS25 to LED terminals on the EV1527DR-02A board.
2. Preset the power supply to 3V - 4.2V.
3. Turn the power supply off.
4. Connect the power supply terminals to:
a. Positive (+): VIN
b. Negative (–): GND
5. Connect EN to VIN.
6. Turn on the power supply after making said connections.
7. The MP1527 is enabled on the demo board once VIN is applied.
8. Drive FLASH of Q1 with a pulsed signal (3V or above for High, 0V for Low) to switch between
two (2) LED currents.
9. IOUT1 is set to 150mA on the board.
10. IOUT2 is set to 750mA on the board.
